To aZZwhom t may concern.-

Be it known that I, JACOB ORT, a citizen of the United States, residing at Vahoo, in the county of Saunders and State of Nebraska, have invented a new and useful Improvement in Doorway-Conformators, of which the following is a specication.

My invention relates to an improved dev ice for use in fitting doors, windows, and the llke, to their casings. With the instruments hitherto employed by carpenters in taking the measurements more especially of door 'casin'gs for the purpose ot' iitting doors therein, it has been a matter of difficulty to lay o the door with such exactness that when trimmed to the measurements marked thereon it will t with desired conformity in its casing; and this especially when the sides of the opening, owing to bad construction, shrinkage or warping of the casing, do not present straight and parallel surfaces.

My object is to provide a conformating instrument, of light, simple, and comparatively inexpensive construction, whereby the measurements of a door opening may be taken and marked upon the door, quickly, accurately, and with comparatively little labor.

In the drawings-Figure lis a view in elevation of a door casing, showing my irnproved conformator applied thereto; Fig. 2, a broken plan view of an extensible arm of the device; Fig. 3, an enlarged section taken on line 3 of Fig. 2; Fig. 4., an enlarged section taken on line 4 of Fig. l; and Figs. 5 and 6 enlarged perspective views of details of an adjustingand retaining mechanism for changing the angle between the main or staff portion and the arm of the device.

The device consists, broadly, of a staif A, formed of relatively extensible and contractible members ts, to one end of which is pivoted an arm B, formed of relatively extensible and contractible members q p, and an adj usting and retaining connection C for chang ing the relative angles of the stad and arm. In the end of the part t adjacent to the part s is a recess, covered by a plate t to receive the end portion of a slide r which is held to the mem ber t by screws r passing through the plate t. Extending longitudinally through the member s is a recess s adapted to receive the slide r. At the end of the member s adjacent to the member tis a clamp comprising a springy plate s2 fastened down at one side of the recess s. A thumb screw s3 passes through the free end portion of the plate s2 into the part s, whereby the plate may be tightened against the slide r to hold the members in relatively adjusted position. At the opposite ends of the staff on its outer side are abutting shoulders t2 s4, respectively, presenting rectangular surfaces, and giving to the staff the characterof a straight edge. Between the ends of the sta, in the locations shown, are adjustable gages or gaging screws t3 t3, extending transversely through the members t s respectively. The arm B is pivotally connected at one end of its member q to a lug t4 at the end of the member t, to swing only in the plane of the staff. In the outer side of the opposite endportion of the member q is a groove q' receiving the shank portion p of the member p, which slides longitudinally therein. The shank p carries a clamp screw p2 which passes through a longitudinally extending recess q2 in the inner side of the member q. Tightening of the screw p2 causes it to clamp the members together in relatively adjusted position. At the outer end of the member p is an abutting shoulder p3 presenting rectangular surfaces giving to the arm the character of a straight-edge. The adjusting and re taining connection C is preferably in the form of a rod n pivoted at one end to the member q of the arm, and threaded alongits opposite endportion to receive a nut orinternally threaded traveling thumb wheel n. Fastened upon the side of the member t of the staff is a plate n2 having two recessed lugs n3 affording between them a socket to receive the thumb wheel 'n'. The rod n carrying the wheel n is sprung into the recesses of the lugs n3 and its resilient tendency holds it in place and the wheel n between the lugs. Turning of the wheel moves the rod longitudinally to swing the arm B to different angles with relation to the staff.

In operation the device is placed in the opening to be measured with the abutting shoulders t2 s4 against the jamb. The staif members are then extended until they bear at opposite ends against the sill and lintel, and are secured in adj usted position by tightening the screw s3. The members of the arm B are IOO and by turning the thumb wheel n to cause the abutting shoulder p3 to extend against the lintel and opposite face of the casing. The gaging screws t3 may then be turned, if necessary, to adj ust them againstthe adjacent surface of the jamb so that any inequality in the latter may be measured. On the member t I provide a"lug t5 and in the member s a gain S5, at the places indicated, for locating the hinges, the points of location being marked upon the casing while the device is in place. The device is removed from the casing without disturbing its adjustments and laid upon the door to permit the points thereon registering with the abutting shoulders, and gaging screws to be marked, for the outline of the door. The locations of the hinges may also be marked at the same time. By reversing the device so that the staif A is against the opposite side of the casing and the arm B against the threshold the outline for the remaining two edges of the door may be taken. If desired an arm corresponding with the arm B may be provided at the opposite end of the staff whereby the threshold measurement may be taken simultaneously with that of the jamb and lintel.

In the use of my improved couformator, the height, width and shape of a door opening and the location of hinges may be quickly and accurately taken and marked upon the door. By removing the screws o", and sliding the bar o" into the member s, and springing the rod n out of the plate so that the arm B may swing against the member t, the device' may be readily placed in a carpenters -tool chest. The device offers facilities for taking the measurements more quickly than has been possible with the instruments hitherto commonly employed, and furthermore affords a safeguard against mistakes which were liable to occurin the use of the said instruments.

While I prefer to construct my improved conformator as shown and described, it may be modied in the matter of details Without departing from the spirit of my invention as defined by the claims.

What I claim as new, and desire to secure by Letters Patent, is

l. In a doorway conformator, the combination of a stad affording a straight edge, and formed of relatively extensible members, an arm affording a straight edge pivoted at one end to an end of the sta and formed of relatively extensible members, an adjusting and retaining connection between the stad and arm, and securing means upon the sta and arm for holding their members in relatively adjusted position, substantially as and for the purpose set forth.

2. In a doorway conformator, the combination of a stad formed of relatively extensible members, an arm pivoted at one end to an end of the staff and formed of relatively extensible members, an adjusting and retaining connection between the stad and arm, fastening means upon the staff and arm for securing their members in relatively adj usted position, and straight edge abutting shoulders, respectively at the opposite ends of the staff, and the outer end of the arm, substantially as and for the purpose set forth.

3. In a doorway conformator, the combination of a staff, formed of relatively extensible members, an arm pivoted at one end to an end of the staff and formed of relatively extensible members, an adjusting and retaining connection between the staff and arm, fastening means upon the staff and arm for securing their members in relatively adjusted position, straight edge abutting shoulders respectively at the opposite ends of the staff and the outer end of the arm, and an adjustable gage t3 on the staff between its ends, substantially as and for the purpose set forth.

4. In a doorway conformator, a staff A affording a straight edge comprising a member t provided with a removable slide r, and a recessed member s, to receive the slide, provided with clamping mechanism for the slide, an arm B affording a straight edge comprising a sliding member p, and a recessed member q, on which the member p slides,pivoted at one end to the end of the staff member t, securing means upon the arm for holding its members in adjusted position, and an adjusting and retaining connection between the staif and arm, substantially as described.

5. In a doorway conformator, the combination of a staff affording a straight edge and formed of relatively extensible members, an arm affording a straight edge pivoted at one end to an end of the staff and formed of relatively extensible members, and an adjusting and retaining connection between the staff and arm comprising a socket plate upon the stad, a threaded rod on the arm, and a traveling nut upon the rod engaging the socket plate, substantially as and for the purpose described.

6. In a doorway conformator, the combination of a staff, affording a straight edge, formed of relatively extensible members and provided toward opposite ends with hinge loeating means, an arm, affording a straight edge, pivoted at one end to an end of the staff, and formed of relatively extensible members, and an adjusting and retaining connection between the staff and arm, substantially as and for the purpose described.
